Yep I'm the Daryl that flew the Jabiru Tailgragger last year on Megafauna And you are correct Barbara and Robin are with the group....unfortunately I'm not. Just posting info on the webpage as it comes back to me from the group. CHEERS Daryl Hooke Jabiru SPT-3300 19-3587

On June 1st a group of four Jabiru's started out from Gippsland in Victoria to fly around Australia. I have set up a web page so that interested parties may track their progress. The group have been stuck in northern Queensland for over a week now due to inclement weather. If you wish to check on the group's progress see http://www.darylhooke.com/oz/ CHEERS Daryl Hooke [email protected]

David, Jabiru have produced, through a service letter, the optimum air/fuel mixture ratio for given engine RPM. The two graphs have a grey area which depicts the optimum air/fuel ratio as listed by Jabiru. The first graph shows measurements (blue line) outside the optimum and running too lean. (My original jetting) The second graph shows the blue line inside the grey shaded area after rejetting the carby. CHEERS Daryl

No the probe is fitted for testing only and the system is completely portable. Probe life between 50 - 500 hours on leaded fuel and replacement cost around about US$80.00

Aviators, As most of you would be aware, Jabiru have recently released JSL002-2 updating the recommended carby jetting for 2200 & 3300 engines. In the service letter, recommended air/fuel mixture ratios (Lamda) are given for various engine RPM. I decided rather than "play" musical jets, I would purchase a Lambda meter and measure my air/fuel mixture ratios. I made up a proforma using the Jabiru recommended Lamda values as my reference, fitted the Lamda meeter and went flying. Fig 1 shows the readings with the original jetting of 250 Main and 285 Needle jets. (3300 engine) If you look at the graph in fig 1, it shows the engine running lean in cruise. I then fitted the mid range jets as recommended in the Jabiru Service Letter (255 Main & 290 Needle) and the results are shown in fig 2. I now burn 3 l/hr more and find CHT much lower on the ground, in cruise and climb. Hope this is of some help! CHEERS Daryl Jabiru SPT-3300

Unless it's a taildragger Ian!

WONT TURN THROUGH 90 DEGREES I fitted one of these and found it was hiting something internally when I tried to lock it over on the bayonet fitting. Now gone back to the original drain plug. Have the quick drain in the top of my toolbox if anyone wants one. Daryl Hooke SPT-3300

Service Bulletin JSB011-1 Inner Seatbelt Attachments has been posted on the Jabiru Website Very important as it has a 20 hour compliance.
